Audio Cable Adapters?

[LoTech]

SETUP: Sometimes when running a line-level feed from one side of the room to the other, I connect two cables together via an adapter. It’s usually a gender changing adapter such as RCA female/female. In this particular case, the signal is not digital. It's the LFE audio for my sub-woofer.

QUESTION: Has anyone had a problem with poor connections, line noise or RF bleed-through doing this?

Also, what is the longest you might recommend running a line level signal?

Thanks for your input.

There should be no problems with the kind of lengths you would have in a home, assuming good shielded cable. What are you using? The connectors are not going to be the most reliable if you are using RCA. Most long runs are best done with coax, and for joining two cables just use a similar but more reliable F barrel connector.

A gender changer has male on one end and female on the other, BTW. What you are using is a barrel connector aka splice.

I need to run about 50ft of wire to connect to a sub-woofer. Most standard sub-woofer cables are RCA and male on each end. What I mean by gender change, is a RCA female-female barrell type adapter to connect two 25ft cables. At the time, I do not have a problem. I'm trying to make uyp my mind if I want to order a single 50ft run of cable (my first choice) or two 25ft runs with an adapter in the middle. MonoPrice.com has a 50ft run for $9.74.

The subwoofer signal from an AV Receiver can be too weak to get through a poor cable. I had this happen to me when I purchased a new AVR. The new one didn't work, while the previous one did. I bought a new cable and all was fine.

You can try the two cables with adaptor and see if it'll work, or simply purchase a new Sub cable from Monoprice - the one I purchased is quite good and it's inexpensive for the security of a good cable with good shielding.

You can also make a subwoofer cable from RG6 (fairly stiff coaxial cable) and the correct connectors at each end.
